For China and the global space industry, this is a “great scientific achievement”. < p > < p > after 23 days, chang’e-5 has successfully carried lunar samples back to earth after overcoming many difficulties, such as Earth Moon transfer, near moon braking, lunar circle flight, lunar landing, automatic sampling, lunar take-off, lunar orbit rendezvous and docking, and reentry. CUSI said the task required very precise control and was technically difficult. < / P > < p > “China has become an aerospace power, which is the consensus of global aerospace experts. For more than 40 years, scientists in the global aerospace field have been hoping to study the lunar soil more deeply, and believe that the success of China’s chang’e-5 will help them solve their puzzles. ” CUSI said. < / P > < p > he pointed out that in recent years, China has developed rapidly in the field of aerospace, and he believed that China will continue to explore other planets, including Mars, in the future. < p > < p > CUSI has visited China many times before, expressing appreciation for the cooperation between China and Egypt in the field of aerospace. He said that according to the agreement signed by China and Egypt, China will provide assistance for Egypt to establish its first satellite assembly and integration test center, which has been implemented since 2017. It is reported that after the completion of the construction work, China will send experts to install the corresponding equipment and train Egyptian technicians. At present, China has transported the required equipment weighing about 250 tons to Egypt. < / P > < p > in addition, in January 2019, Egypt and Egypt signed the implementation agreement of egypt-2 satellite in Cairo. Egypt-2 satellite cooperation project includes a small remote sensing satellite, a ground measurement and control station and a set of ground application system. The design service life of satellite is 5 years, and that of ground TT & C station is 15 years. At present, Egypt’s satellite assembly and integration test center and Egypt’s No.2 satellite project are going on at the same time. By the end of 2021, Egypt is expected to have its first satellite assembly and integration test center. After that, the egyptian-2 satellite will be assembled at the center and is expected to be launched from China in September 2022.
